Autopano Video - Rendering

This is the window in which you define your exportation settings for the final 360° video. Several encoding options are available such as uncompressed, frames, H.264.MP4, Cineform MOV & AVI and ProRes MOV.

From AVP 3.0, whenever a user imports an Autopano Video Pro project into Nuke, their nodes will be created automatically, providing a seamless workflow they can immediately apply to Cara VR. With a robust bridge between the two apps, Foundry and GoPro customers can access the right tool for the job, at every stage of their workflow.

  • This is the size you wish to have for your output, but the final size is going to be dictated by the type of export:
    • If you choose a frame export you will have pictures of the size specified here
    • If you choose an uncompressed AVI export you will have a video of the size specified here
    • If you choose an H.264.MP4 export, the maximum size will be 4K and downsized depending on the preset you use. In this case this is better to let this setting by default to his maximum.
    • If you choose a CineForm MOV & AVI export you will have a video of the size specified here
    • If you choose a ProRes MOV export you will have a video of the size specified here

Timecode Reference NEW

  • When importing videos from any genlocked RIG, you do not need to synchronize the videos again.
  • Let's you choose your start time in the combo box


  • Output type: uncompressed (AVI), frames, H.264.MP4, Cineform MOV & AVI or ProRes MOV
  • Output path: enter the output name and path desired

Output type

MP4 export (H.264)

H.264.MP4 export

Encoding rules

  • Preset:
    • H.264 HD: automatically selects the most appropriate H.264 profile from 2K (1920x1080) to the most basic profile depending on your input size
    • H.264 4K: appropriate for final videos with a maximum size of 4096x2048 pixels
    • H.264 4K Cinema: appropriate for final videos with a maximum size of 4096x2160 pixel
    • H.264 4K UHDTV: appropriate for final videos with a maximum size of 3840x2160 pixels
    • H.264 Blu-ray: corresponds to BluRay quality (1920x1080 pixels)
    • Custom profiles: you can create your own profile by duplicating one these default profiles, see Preference - Render

We recommend to use UHD if you play the video on a desktop, HD if you play it on a mobile or publish it on a web server

  • Standard/FPS:
    • As preset: forces the Standard setting defined in Settings, Preset tab
    • As original video: keeps the standard of the source videos
    • PAL/NTSC and images/second
  • Video bitrate: lets you choose the bitrate you want
  • Audio bitrate: lets you choose the bitrate you want
  • Aspect ratio:
    • Keep in pixel size: the final video is automatically resized to respect assembly proportion
    • Keep in display info: (by default) the aspect ratio in pixels is not necessarily respected, but the information is kept in the video feed to all correct display. Some video players do not support this information and may display poorly
    • Do not keep: uses the maximum size available without keeping assembly proportion
  • Audio source: chose the input audio used for the final render.

Cineform MOV or AVI

Cineform MOV&AVI export

Cineform is probably the best encoding/format for an efficient and professional workflow. You can output more than 4K images and keep the input frame rate. There are 3 presets for the Cineform output:

  • GoPro Cineform High 444: RGB444, with high quality compression, almost lossless
  • GoPro Cineform High 422: YUV422, with high quality compression, almost lossless
  • GoPro Cineform Medium 422: YUV422, with low quality compression

On Windows you can choose between an AVI or a MOV container. On Mac, MOV is the only option.

ProRes MOV

ProRes MOV export

ProRes presets:

  • Apple ProRes 422 Proxy
  • Apple ProRes 422 LT
  • Apple ProRes 422
  • Apple ProRes 422 HQ
  • Apple ProRes 4444
  • Apple ProRes 4444 XQ

See how to render with an Alpha channel here

Uncompressed export

This export is rendered at the size specified previously. It will give you an uncompressed AVI file.

Be careful with the size of the file, for example 15 secondes @ 4320x2160 take 20 Gb of space.

uncompressed export

  • Audio source: chose the input audio used for the final render.

Frame export

This export is rendered at the size specified previously. It will give you JPEG, TIFF or PNG files.

Frames export

  • Format
    • File format: chose the type of picture files you want: JPEG, TIFF or PNG
    • Depth: chose the color depth of your output image: 8 or 16 bits, only available with TIFF and PNG
    • Compression: chose the compression of your output image
    • Remove Alpha channel: Deletes the alpha channel of the exported files.
    • Keep timeline numbering for output names:

Timecode Reference NEW

AVP 3.0 now supports timecode which allows videos from any genlocked rig to be directly imported into Autopano Video Pro without the need to synchronize the videos again. On the export side of things, you can either choose your start time in the render box or pass-through the source timecodes. The burn-in function will also help you work with proxy files in post-processing. This feature works with solutions offered by 3d-party companies like Timecode Systems, and results to a faster and more precise workflow.

  • Disabled
  • Start at "00:00:00:00"
  • Start at "00:00:00:01"
  • Use "custom" Timecode Reference: Let's you enter your own values
  • Use "passthrough" Timecode Reference

General options

  • Restore Defaults: restores the default setting of the current tab.
  • Apply: validates the modifications made to the settings without launching output.
  • Cancel: cancels changes and closes the output settings window.
  • Render: sends the job to the batch render and launches the final output of the 360° video.

Batch render@2x.png Batch render window

Batch render window

Add project icon Add a project (.kava): You can add a project or just drag & drop a .kava file to the Batch render window directly
Remove project icon Remove a project: You can remove a project
Start render Pause render Stop render: Play / Pause / Start the render

You can now re-organize your batches by moving them up or down in the list

Rendering information

Once the video is rendered, the render window display some statistics measured during the computation which are decoding, rendering and encoding.
Those statitics can help you understand how CPU/GPU work and can also help you optimize your hardware and AVP settings.

Rendering stats

In this example (Radeon R9 M370X 2Gb):

  • Decoding is at 15%: I/O transfer rate is low and is not a limiting factor (integrated SSD used)
  • Rendering is at 89%: The GPU drives the performance
  • Encoder is at 98%: CPU is used as the output file format is MP4

Note: If one of the areas is around 100% while the others are much lower (< 50%), it means that this part of the process is the limiting factor to get better performance.

Some advice:

  • Decoding is at 100%: I/O is most certainly the limitation. Prefer a local drive, or use SSD or change the input file format for a faster decoding
  • Rendering is at 100%: The GPU drives the performance. Better GPU, better global rendering time
  • Encoder is at 100%: Sometimes, the GPU drivers are not behaving well with texture transfers. If it doesn't change anything, just use another codec as output format, for example, Cineform

Also, consider upgrading to Autopano Video Pro which supports GPU processing for quicker preview/faster rendering times!

Be aware that CPU is used with MP4 and Cineform encoding or if your video output exceeds 8192 pixel wide

Batch rendering - command line

Command line rendering: You can add one job to the batch rendering queue through the command line, without opening the software. It will render that job and quit the software when finished. If you have a render farm and want to use AVP for massive rendering, you can do it now with this option: AutopanoVideo -batch filename.kava
